Connected Discourse TrackingPress F10 to open the "Option" window and Select the “Speech Tracking” tab. Enable Self-paced Connected Discourse function and the appropriate setting. Then the listener can perform the openset speech recognition test. Also, the user can click the “TRACK” button in the top toolbar to enable the speech tracking function. In the “Speech Tracking” mode, the text of the sentences will not be shown, and the user is required to type the answer in the bottom of the window. Generate Noisy SpeechPress F7 to open the "Background Noise Setting" window and Specify the Noise Type and desired signal-to-noise ratio, then click "OK". Then click “Run” button or Press F2 to start the testing. Noisy speech signals will be generated in real time according to the noise type and desired signal to noise ratio.Cochlear Implant SimulationPress F6 to open the "Speech Processor Design" window and Enable the "Noiseband Vocoder Processor" and Specify the Parameters, then click "OK". Then click “Run” button or Press F2 to start the testing. Vocoded speech signals will be generated in real time according to the parameters specified in the vocoder setting (e.g. the number of spectral channels). The background noise setting and vocoder setting can be combined so the program can test vocoded speech sigansl under various listening conditions, such as different background noise and signal-to-noise ratio. Real-time Result View and PrintDuring the test, the user can drag the line in the left to view the recognition performance and correctly recognized words and sentences in real time. After the whole test is completed, the screen also shows the final detailed results, including the percent correct, sentence lists etc. Also, all these detailed test results can be printed out by press “Ctrl+P” or Press the “Print” button in the toolbar (2nd button in the toolbar). If the user wants to record the listeners’ response, simply click “Input” button in the toolbar (#3). One input window will appear and the user can type all the words produced by the listener.Stereo Output ConfigurationThe programs allows the user to configuration the source of speech and noise in the test. Press F10 to open the "Option" window and Select the “Background and Stereo Output” tab. Enable Stereo Output of target speech and interfering speech/noise. Then select the Stereo Output Configuration accordingly. There are four choices in the configuration, including mixed mono, speech left/noise right, speech right/noise left, random channels.Spatial Hearing TestThe programs allows the user to setup spatial hearing test. Using ASIO-based driver, speech signal can be delivered in a specific channel while the noise can be delivered to multiple speakers. Press CTRL+F10 to open the ASIO control pavel.
